Beginner Configuration Help

[CodeMan99]

👋 Hello,

I'm totally new to helm in general. Hopefully there is some documentation you can point me toward.

I'm trying to follow a linode guide to setup a docker registry. It mentions this as an alternative, but I'm not sure how to make it work.

The original example is a configuration with this command:

$ helm install docker-registry stable/docker-registry -f registry/docker-configs.yml
Error: INSTALLATION FAILED: repo stable not found

I am not sure how to correct the error. However, the article mentions helm repo add twuni https://helm.twun.io as an alternative. I'm not sure how to continue from here. I have attempted the following.

$ helm install docker-registry stable/docker-registry -f registry/docker-configs.yml
Error: INSTALLATION FAILED: repo stable not found

$ helm install twuni/docker-registry stable/docker-registry -f registry/docker-configs.yml
Error: INSTALLATION FAILED: repo stable not found

$ helm install twuni/docker-registry docker-registry -f registry/docker-configs.yml     
Error: INSTALLATION FAILED: non-absolute URLs should be in form of repo_name/path_to_chart, got: docker-registry

$ helm install twuni/docker-registry                                        
Error: INSTALLATION FAILED: must either provide a name or specify --generate-name

$ helm install twuni/docker-registry -f registry/docker-configs.yml 
Error: INSTALLATION FAILED: must either provide a name or specify --generate-name

A friend helped me enable the stable repository.

$ helm repo add stable https://charts.helm.sh/stable
"stable" has been added to your repositories
$ helm install docker-registry stable/docker-registry -f registry/docker-configs.yml 
WARNING: This chart is deprecated
Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: resource mapping not found for name: "docker-registry" namespace: "" from "": no matches for kind "Ingress" in version "extensions/v1beta1"
ensure CRDs are installed first

Now I have a nice deprecation warning (which the linode document mentioned) and wonderful error. I'm not sure what extensions/v1beta1 is.
